Abstract
The present disclosure provides a source driving circuit, a driving method, and a display device. The source driving circuit includes a gamma generating circuit, a gamma regulating circuit, and a control circuit. The gamma regulating circuit is configured to determine, according to a plurality of gamma reference voltage pairs, a first output voltage, a second output voltage, a third output voltage, and a fourth output voltage corresponding to each of the gamma reference voltage pairs. Further, the control circuit is configured to perform driving and displaying with the first output voltage in a first image frame, with the second output voltage in a second image frame, with the third output voltage in a third image frame, and with the fourth output voltage in a fourth image frame.
